“I need to smoke some more pot to figure out how to use this thing.”

86% of 115 verified owners recommend the Boss Katana-50 MkII, based on real owner verdicts aggregated from Reddit, enthusiast forums, and YouTube.
Affiliate blogs here say 100% recommend, while the owner-based score is 86%. They earn a commission on every sale — so we show them for transparency but never let them move the score.
The headline score reflects owners (Reddit, enthusiast forums), independent lab tests, blogs with no affiliate links, and YouTube owner-comments when they line up with owners. YouTube and Affiliate blogs are shown for perspective but kept out here — hover the i for why.

“I need to smoke some more pot to figure out how to use this thing.”
“Boss nailed it with this amp.”
“On the Katana, the 'lead' channel is too fizzy.”
“I was so convinced by their practicality that I bought one a couple of years back. However, I ended up selling it, because I only used it a couple of times.”
“Sounded digital without much punch at all which was a surprise as I expected so much more”
“Really my best purchase ever”
“i find the hybrids sound much closer to "real" amps then the Boss”
“The only thing I think is BS with the Katana's is the 100w you get eight preset channels and the 50w you get four preset channels.”
“My band mates keep telling me how good my Katana sounds in a room full of Marshall and orange amps.”
“Gave up with mine, too complicated for a non geek.”
“I’m not crazy about the OD/drive settings, but the clean tone is ridiculously beautiful.”
“What an incredible difference!”
“Best amp purchase ever.”
“I had similar issue with my Katana 50mkII. When I switched to a Marshall20DSLHr+Cabinet, and all was much better”
“If the 50w just had an effects loop and could use the footswitch it would be perfect.”
“it sounded horrible out the box....steep learning curve but it's not bad at all once you dial it in.”
“I have tried both the Mk1 and Mk2 50's in store and we did not get along.”
“I was impressed by the amp”
“we just thought it sounded really good when I was playing in the store”
“Two things make me hesitate - 1. The clean channel seemed to require full volume”
“Gets thin, sometimes disappears in the mix.”
“Been using the USB out for my covers and it sounds good enough for me”
“It's almost TOO fizzy/gainy and hollow.”
“it's the best solid state amp I've ever heard!”
Practical notes owners raise — setup, quirks, and issues to watch for. They don't say whether the person likes the product, so they're not counted in the score, but they inform the pros, cons, and who it's for.
“50MKII is super bright, totally the opposite of muffled. Most of the time I try to boost lower frequencies in EQ to make it sound more bottom.”
“There’s really no difference between the plain 50mkII and the artist MKII. As long as you have tone studio the only thing you’re really paying for is the Waza speaker”
“Generally, there is a big difference with the stock amp presets but to me, it made a noticeable improvement after I spent some time balancing the gain.”
“The 100w can play as loud the 50. It got a power limiter from 0.5w to 100w and an headphone plug. Moreover the 50w don't have the same speaker, the 100w is more round sounding.”
“YES. Use alternate mode though. The default sounds like crap in comparison.”
